The insurer unsuccessfully moved for summary judgment seeking to reject the insured's collapse claim. Gnannn v. United Servs. Auto, Ass'n, 2019 Conn. Super. LEXIS 1955 (Conn. Super Ct. July 11, 2019).

The insureds' home was built in 1985 and they purchased their home in 1993. A home inspection reported that some settlement and curing related cracks existed in the slab floor, but no signs of abnormal settlement were noticed. The concrete walls were in overall good condition.

In 2015, the insureds became aware of abnormal cracking in the basement. USAA was informed of the claim but denied coverage in October 2015. The insureds sued USAA. After suit was filed, the insureds hired an engineer, David Grandpre, to inspect their home. He observed severe cracking in the basement walls caused by an expansive chemical reaction within the concrete. The structure was not in imminent peril of falling down, and it continued as insureds' residence. But Mr. Grandpre noticed bulging and bowing, evidence that the concrete basement walls had failed and had begun to move inward due to the lateral pressure of the soil outside the home.
